ooMrosrrn LEATHER HEEL.

Application filed May 4,

My invention relates to improvements in heels for attachment-to boots and shoes: The ob]ect of my invention isto produce a simple and durable heel which can be ap- 1 plied to av boot or shoe precisely like the ordinary heel and which a cushion heel exceedingly comfortablcto the wearer and con'ibining the good qualities of leather and rubber. i

Many wearers of cushion heels prefer a.

leather tread and many prefer the rubber. My improvement isintended to satisfy both classes of wearers.

The object of my invention is to produce a heel which will have a leather top lift,

'd'ency for the top lift or leather part 10 to a rubber or cushion back for the top lift and with the rubber projecting through and anchored in the leather and dispo ed so as to -1nake a series of rubber gripping surfaces near the edge portions of the top lift. I arrange. these anchoring rubber parts so that the fastening nails go through them and in a manner toprevent the nail heads over comin in contact with the ground. Thus the rubber bosses or projections will give a sufficient gripping surface on slip pery places when the ground is dry, the leather will take on such places when the ground is wet, and the backing will give the desired cushioning effect.

My invention is further intended to have the. leather and rubber components of my improved heel united in such a way that the parts cannot slip with relation to each other and the slipping or sliding strain on the top lift taken largely away from the fastein ing nails.

My invention is further intended to pro duce a heel which can be used in the usual way and which will have a better a1. ')pearance than many heels now in use.

Reference is had to the accompanying drawings forming a partof this specification in. which similar referencecharacters refer to similar parts throughoutthe several views. e

Figure 1 is a face view of the top lift forming a part of my invention; :7 Figure 2 is an inside view of the top lift, and

Figure 3 is a section on the line of Figure 2, but showing the top lift united with its cushion back.

The top lift 10 is made of sole leather;

and is of the desired heel shape. united at its back with the cushion lift or from the cushionll which substantially fills 1926. Serial No. 106,646. I

body 11 of rubber. The top lift is provided Wlilll a series of holes 12 located near the edge and these holes are countersunk and reamed. out at the outer portion of the lift; as shown at 13 and the fastening nails 14 go throughthe holes 12 and throughthat portion of the rubber which fills the holes In uniting the parts 10 and 11 they are put together under pressure when the rubher is plastic and before 'ulcanizing so that the rubber enters the holes 12 and fills the spaces 13, except for enoughspace to provide for the heads of the nails 14.

When heels have been'inade of rubber and leather heretofore, there has been a tenslide with relation to the part 11 and bring all the lateral strain on thefastening nails 14h To obviate this I provide a series of recesses 15 in the back of the top lift 10 which are preferably arranged in crossing rows as in Figure 2, although they may be disposed in any desired manner. It-will be seen that when the rubber and leather'are forced together as shown in Figure 3, the rubber will fill the recesses '15 and beanchored firmly therein and thus tend :to better unite the parts 10 and 11 andto prevent any slipping or sliding movements of said parts with relation to each otheiz,

. The heel is attached to a base portion 17 of a shoe or boot precisely as usual by the 1 nails 1e and it will be noted that the rubber the holes 12 and 13. extends to the tread surface of the top lift and thus a row of these plugs or parts eiitend around the heel near the edge portion forming an excellent gripping and cushioning surface.

it will be noticed that as the top lift is essentially of leather, it can be reinforced against wear either withslugs or otherwise, precisely like the ordinary leather heel.

A composite cushion heel comprising a! leather-top lift having holes therethrough near theedge, said holes being enlarged at their outer parts, and a rubber back or body for the toplift having the rubber extended into and filling the aforesaid holes which are 'dispo-ed to receive fastening nails.

In testimony whereof, I have signed my p name to thisspecification this 30th dayof April, 1926. i i
